As of today, the latest version FSP (gold4) for BayTrail misses the
PAD configuration of the SD controller's Card Detect signal. The
default PAD value for the CD pin sets the pin to work in GPIO mode,
which causes card detect status cannot be reflected by the Present
State register in the SD controller (bit 16 & bit 18 are always zero).
Add a configuration for this pin in the pinctrl node.
Note I've checked the PAD configuration for all the pins in all the
3 controllers (eMMC/SDIO/SD). Only this SDMMC3_CD_B pin does not get
initialized to correct mode by FSP. With fsp,emmc-boot-mode set to
2 (eMMC 4.1), eMMC pins are initialized to func 1, but if we set
fsp,emmc-boot-mode to 1 (auto), those pins are initialized to func 3
which is correct according to datasheet.

Newer stepping SoC integrates an eMMC 4.5 controller. Intel FSP

eMMC controller it initializes. Instead of hardcoded to 2, now
we change it to 1 which means "auto".

Currently the AHB1 clock speed is configured as 200MHz by
the SPL, but this causes a subtle and hard to reproduce data
corruption in SRAM C (for example, this can't be easily
detected with a trivial memset/memcmp test).
For what it's worth, the Allwinner's BSP configures AHB1
as 200MHz, as can be verified by running the devmem2 tool
in the system running the Allwinner's kernel 3.10.x:
0x1C20028: PLL_PERIPH0_CTRL_REG = 0x90041811
0x1C20054: AHB1_APB1_CFG_REG = 0x3180
0x1C20058: APB2_CFG_REG = 0x1000000
0x1C2005C: AHB2_CFG_REG = 0x1
However the FEL mode uses more conservative settings (100MHz
for AHB1):
0x1C20028: PLL_PERIPH0_CTRL_REG = 0x90041811
0x1C20054: AHB1_APB1_CFG_REG = 0x3190
0x1C20058: APB2_CFG_REG = 0x1000000
0x1C2005C: AHB2_CFG_REG = 0x0
It is yet to be confirmed whether faster AHB1/AHB2 clock settings
can be used safely if we initialize the AXP803 PMIC instead of
using reset defaults. But in order to resolve the data corruption
problem right now, it's best to downclock AHB1 to a safe level.
Note that this issue only affects the SPL, which is not fully
supported on Allwinner A64 yet and it should not affect the boot0
usage (unless somebody can confirm SRAM C corruption with the
boot0 too).
